Oscillators

An oscillator is a composed of components that create a periodic circuit. The frequency of the created waveform can range from very low to high and it varies depending on the type of oscillator. Oscillators are used for analog signal generation, frequency synthesis, frequency control, and for frequency filtering.

ABDFVCTCXO-20.000MHZ-L-2-T5 is one such oscillator. The ABDFVCTCXO-20.000MHZ-L-2-T5 oscillator has a specified frequency of 20.000 MHz with a tolerance of ±1 ppm, an operating temperature from 0°C to 70°C, and a supply voltage of 3.3V. It is a two-wire oscillator, meaning that it only requires power and ground for operation.

Application Field and Working Principle

The ABDFVCTCXO-20.000MHZ-L-2-T5 is suitable for a range of applications, such as telecommunications, GPS, and other applications where a stable frequency is required. The oscillator is also used as a reference clock for high speed digital logic chips, such as microprocessors, memory controllers, and ASICs.

The ABDFVCTCXO-20.000MHZ-L-2-T5 utilizes a temperature compensated crystal oscillator (TCXO) as its frequency source. A TCXO is made up of a quartz crystal that is temperature compensated in order to maintain a stabilized frequency output. The crystal is connected to two electrode plates which then allow for an alternating current (AC) signal to pass through. This AC signal is then amplified by an amplifier and filtered to produce a waveform at the desired frequency. The output frequency produced by the TCXO is then monitored and adjusted by a temperature compensator in order to maintain the specified frequency.

The ABDFVCTCXO-20.000MHZ-L-2-T5 also utilizes an onboard microcontroller that is used to monitor and adjust the temperature and supply voltage, in order to maintain a constant output frequency. The microcontroller can also provide additional features such as frequency calibration, trimming, and locked loop control.

The ABDFVCTCXO-20.000MHZ-L-2-T5 is a reliable, low jitter oscillator that is suitable for many applications. Its high frequency stability, low power consumption and low price make it an attractive choice for various applications requiring frequency control.
